PURPOSE:To provide a light control body which has no change in transparency and has excellent formability and light controllability of a light control surface and prevents deformation by forming the light control member of a silicone resin and joining the light control member to a glass base plate via the spacing provided therebetween by a projecting part provided at least to one of the members and the base plate. CONSTITUTION:A base plate 1 consists of a transparent glass plate having a flat plate surface and is formed into a disc shape. A light control member 2 consists of a silicone resin having transparency, heat resistance and resilience and is formed of a plate-shaped body. A light control surface 3 is formed on one surface of the member 2 and a projecting part 6 which forms a spacing 5 between the two plate surfaces in contact with the plate surface opposite to the plate 1 is formed on the other surface. There are no inclusions such as adhesive agents between the member 2 and the plate 1 and the transparency is satisfactorily maintained; further both opposed surfaces are formed with the spacing by the projecting part 6 to decrease the contact area between the two surfaces, by which the excessive rise in the temp. of the light control member is satisfactorily prevented. |
